Any experience on what are the lightest "power factor" loadings that will reliably cycle a 10mm Glock 20 Gen4 with factory springs?
I have some 135g 10mm Nosler HP projectiles to use up. Higher velocity loadings for them in 10mm produces poor accuracy and a lot of flash and blast.
So, I'm trying to figure out a lower speed loading that would have more accuracy, less flash and blast w/o changing springs.
An example of a lighter 10mm factory loading would be the Federal American Eagle Ammunition 10mm Auto 180 Grain Full Metal Jacket @ 1060 ft/sec published velocity for an IPSC power factor of 191.
I'm thinking something like 135g @ 1350 ft/sec (182 PF) assuming I can find published load data....
